Abstract

A method and apparatus to integrate a plurality of sets of authorized credentials from a plurality of building tenants is disclosed, using networking techniques to allow partitioned access to common resources shared by those tenants.

Claims

1. A method for determining access rights to a select portion or resource of a building having a building access control system capable of selectively allowing access to a portion or resource of the building, wherein said building houses one or more tenants, having one or more tenant-operated access control systems, the method comprising the steps of:

obtaining, at a first computer in signal communication with a credential reader, a first indicium from a tenant credential via said credential reader;

transmitting said first indicium to said tenant-operated access control systems via a pseudo reader in signal communication with said first computer;

if one of said tenant-operated access control systems determines that said first indicium is valid, receiving, at said pseudo-reader, from said one tenant-operated access control system an indication that said first indicium is valid;

upon receipt of said indication,

generating, by the pseudo-reader, a second indicium formatted to be compatible with said building access control system;

transmitting said second indicium to said building access control system; and

thereby allowing access to the selected portion or resource of the building upon receiving said second indicium by said building access control system.

2. The method of claim 1, wherein the step of transmitting said first indicium to said tenant-operated access control systems comprises the step of directing a network based transmission to said pseudo reader.

3. The method of claim 1, wherein the step of transmitting the second indicium to said building access control system comprises the step of directing said signal via a network based transmission.

4. The method of claim 1, further comprising:

waiting for a predetermined time after transmitting said first indicium to receive said second indicium; and

if said second indicium is not received within said predetermined time, denying access to the building or to the selected portion or resource of the building.

5. The method of claim 1, further comprising allowing access to areas leased by a tenant whose tenant-operated access control system provided said indication that said first indicium is valid.

6. The method of claim 1, additionally comprising the step of coding said second indicium to indicate that access should be granted.

7. The method of claim 1, additionally comprising the step of coding said second indicium to indicate that access should be denied.

8. The method of claim 1, additionally comprising the step of coding said second indicium to indicate that access should be granted to a handicapped person.

9. The method of claim 1, additionally comprising the step of denying access to said building or its resources if said first indicium is identical to a valid second indicium.

10. The method of claim 9, additionally comprising the step of coding said second indicium to indicate that access should be denied.

11. The method of claim 1, wherein the step of allowing access to the selected portion or resource of the building includes the step of allowing use of elevators within the building.

12. The method of claim 1, further comprising providing additional audit information to said building access control system.

13. A system for controlling access to select portions or resources of a building, wherein said building houses one or more tenants, said system comprising:

a credential reader capable of receiving a first indicium from a tenant credential;

a first computer in signal communication with said credential reader;

one or more tenant-operated access control systems comprising a tenant interface in signal communication with a pseudo reader;

and

a building access control system in signal communication with said pseudo-reader;

wherein said credential reader provides said first indicium to said first computer;

said first computer provides said first indicium to said one or more tenant-operated access control systems via said pseudo reader to said tenant interface;

one of said tenant-operated access control systems provides a signal to said pseudo-reader if said first indicium is valid; and

said pseudo-reader, on receipt of said signal, provides to said building access control system a second indicium formatted to be compatible with said building access control system to allow access to the selected portions or resources of the building upon receiving said second indicium by said building access control system.

14. The system of claim 13, wherein said signal communication between said first computer and said tenant-operated access control system is provided via a network.

15. The system of claim 13, wherein said signal communication between said one or more tenant-operated access control systems and pseudo-reader is provided via a network.

16. The system of claim 13, wherein said signal communication between said first computer and said one or more tenant-operated access control systems is encoded.

17. The system of claim 13, wherein said building access control system denies access to the building upon expiration of a predetermined period after said first indicium is provided to said one or more tenant-operated access control systems.

18. The system of claim 13, wherein said second indicium comprises coding indicating that access, should be granted.

19. The system of claim 13, wherein said second indicium comprises coding indicating that access should be denied.

20. The system of claim 13, wherein said second indicium comprises coding indicating that access should be granted to a handicapped person.

21. The system of claim 13, wherein said building access control system denies access if said first indicium is identical to a valid second indicium.
